After commit b6d86d3d (Fix DIV_ROUND_CLOSEST to support negative dividends),
the following warning is seen if the kernel is compiled with W=1 (-Wextra):
warning: comparison of unsigned expression >= 0 is always true
The warning is due to the test '((typeof(x))-1) >= 0', which is used to detect
if the variable type is unsigned. Research on the web suggests that the warning
disappears if '>' instead of '>=' is used for the comparison.
Tests after changing the macro along that line show that the warning is gone,
and that the result is still correct:
i=-4: DIV_ROUND_CLOSEST(i, 2)=-2
i=-3: DIV_ROUND_CLOSEST(i, 2)=-2
i=-2: DIV_ROUND_CLOSEST(i, 2)=-1
i=-1: DIV_ROUND_CLOSEST(i, 2)=-1

The per-device PM QoS locking requires a spinlock to be used. The reasons
are:
- an alignement with the PM QoS core code, which is used by the per-device
PM QoS code for the constraints lists management. The PM QoS core code
uses spinlocks to protect the constraints lists,
- some drivers need to use the per-device PM QoS functionality from
interrupt context or spinlock protected context.
An example of such a driver is the OMAP HSI (high-speed synchronous serial
interface) driver which needs to control the IP block idle state
depending on the FIFO empty state, from interrupt context.

[HID: Fix race condition between driver core and ll-driver] introduced
new locking around probe/remove functions that prevents any report/reply
from hardware to reach driver until it returned from probe.
As such, the ask-reply way to checking picoLCD firmware version during
probe is bound to timeout and let probe fail.
Drop the check to let driver successfully probe again (until locking issues
are resolved allowing to reinstate the check).

`insn_rw_emulate_bits()` is used to emulate the `INSN_READ` and
`INSN_WRITE` comedi instructions for subdevices that don't have an
`insn_read()` or `insn_write()` handler but do have an `insn_bits()`
handler.
The function fills in a temporary `struct comedi_insn` called `new_insn`
to pass to the subdevice's `insn_bits()` handler. In doing so, it sets
the `new_insn.data` pointer to point to a temporary data array. This
results in a warning from "sparse" because the `data` pointer in `struct
comedi_insn` has the `__user` tag. The subdevice's `insn_bits()`
handler ignores it anyway as it gets passed a pointer to the temporary
data array in a separate parameter. Don't bother setting
`new_insn.data`; just leave it set to `NULL` (done by an earlier
`memset()`).

For the COMEDI_DEVCONFIG ioctl, the user application may embed a pointer
to firmware data within a designated element (or two elements for 64-bit
pointers) of the `options[]` array in the `struct comedi_devconfig`.
`do_devconfig_ioctl()` calls `comedi_aux_data()` to extract the pointer
value. It needs to be treated as a `__user` pointer so the firmware
data can be copied into kernel memory, so cast the result of
`comedi_aux_data()` to avoid a "sparse" warning. This is not ideal but
`comedi_aux_data()` is called elsewhere in a wholly kernel memory
context so we can't just change its return type to include the `__user`
tag.
